Application January 11, 1954, Serial No. 403,188 6 Claims. c1, 15-146This invention relates to a welders brush holder. In arc-welding theelectrode is held in a holder which is handled by the welder. Thecurrent is turned on, the welder touches the electrode to the work andthen withdraws it a slight distance which initiates an arc. As long ashe holds the electrode slightly spaced from the work, the hot arc ismaintained. This arc melts the electrode and leaves a residue of metalon the joint that is being welded. It is desirable to chip this off andbrush the chips off the Work. To this end I have invented a combinedbrush and chisel holder described and claimed in my prior Patent2,368,988, February 6, 1945. This has been manufactured and sold inlarge quantities over the years following the filing of thisapplication. I have found that I can now improve this tool in severalrespects which will make it more attractive and useful to the man thatdoes the welding. The new design that I am here describing and claimingmakes a stronger and cheaper tool. Referring to the drawings:

Fig. 1 is a side elevation of the tool.

Fig. 2 shows the tool lying on a surface.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is an end elevation taken from the location shown with thenumeral 4 and an arrow.

The chisel is a square section slab 1 of metal tapered down to a bluntedge. Into the end of the slab opposite the blunt end a rod or shank 2is driven into a socket. The holder for the brush comprises a sheetmetal steplike saddle 3. This step-like saddle has at the outer end ariser 4 which has its end turned over at 5 to engage the wooden brushback 6. This brush back has its upper surface 7 slightly curved orarched to cause the ends of the wire bristles 8 to stand in theirassembly on a shallow arc. This makes it more effective when the brushis drawn over the chipped surface. The bottom 9 of the step-like saddlehas on either side an outstanding wing it which serves to contain thebrush at the sides. The bottom 9 has a longitudinally extending rib 9apositioned substantially centrally thereof. The inner end of the saddleis turned down to form a second riser or guard 11 in the step-likesaddle. The outer end of the saddle is arc-welded to the thick end ofthe chisel and the disc-like guard is arc-welded to the shank or rod. Atthe same time the guard is welded to the shank, the end of a coiled Wirehandle is welded to the shank. The other end of the coiled wire handlehas an outstanding eye 12 which forms a hook by which the tool may behung up on a nail or other element. It will be noticed that the seat ofthe saddle is set at an angle to the shank. This is a shallow angle of15 or 20 degrees. This causes the brush to be held on angle to the mainaxis of the tool and we have found that this is the most effectiveposition for the tool to do its work. The work performed by the tool ishard, rough work; consequently, the brush must be securely locked in itssaddle. For this purpose I used a spring end on the clip described andclaimed in my prior patent, but in order to afiord a spring action suchas this required, the whole saddle had to be stamped I ited Stat Pate tout of high carbon steel which can be formed into a member whose endsand side wings will spring back into place after being distorted. Highcarbon steel, from which spring members are made, is much more expensivethan the lower carbon or base metal steel. It was also necessary to finda tool such as a screw driver or some other tool to be forced into theclip-like end member and spring it out to free the brush. I have foundthat a more effective and cheaper way of providing a spring clip at theend of the saddle to hold the brush in place. I perforate the saddle atthree places at the inner end. Two of these perforations take theturned-in feet 13 of the wire spring clip. This clip is formed by apiece of spring wire which is bent to form elbow 14. At the lower end ofthe elbow the wire is formed into two coils 15 of the same type as isfound in a safety pin. This makes the arms of the clip fie'x moreeasily.v This clip in its normal position bears heavily down on the endof the wooden back of the brush when that has been inserted in place.The brush is held very firmly in place and will never be released inordinary practice except when the upper end of the clip is withdrawn andthis can be easily done by using a tool, preferably one of thearc-welding electrodes 17, that will always be at hand. This electrodecan be inserted in the third opening 16 in the seat of the saddle. Thebody of the electrode 17 can be passed through the elbow loop 20 of theclip as shown in Fig. 1 and the electrode used as a lever to pry theclip backward to release the brush. The same operation can be used inopening the saddle to take the brush back. If a lighter spring is used,the thumb may be used to open the clip.

The turned-down riser or guard 11 of the saddle forms a member to arrestthe hand of the welding operator so it will not slip and possibly getinjured in using the tool. The guard has another useful function inholding the handle spaced from the surface on which it rests when not inuse. This is helpful to the welder in picking up the handle. Thesewelders wear heavy gloves which are very cumbersome, and it is difficultto manipulate the gloves to pick up any article, but with the spacingafforded by the guard the handle is in much better position to be pickedup by the welder.

What I claim is:

l. A welders brush holder having in combination a shank, a handlesecured to one end of the shank, a metal saddle provided with a bottom,said saddle being secured to the other ,end of the shank and secured toan intermediate portion of the shank near the inner endof the handle,the saddle intermediate the ends provided with turned-up wings tosecured and anchor the brush at these locations and a spring wire clipsecured to the bottom of the saddle at the inner end, the clip being setinto the metal of the saddle and normally bearing down on the back ofthe brush when the brush is in place, said clip having a turned-backangular portion which may be pressed on to relieve the end of the brushso it may be freed from the saddle, and the clip being a safety pin typeof member with an upper portion in the form of an elbow and a forearmwhich forms a loop, the central portion of the wire clip having thesafety pin type coils and the remainder of the clip in the form of legswith turned-out feet which are hooked in perforations in the bottom ofthe saddle to anchor the clip in place.

2. The combination claimed in claim 1 with the bottom of the saddleprovided at the inner end with a perforation to take a tool which may beinserted after having passed through the loop of the forearm of the wireclip to thereby .use the tool as a lever to pry open the clip to releasethe brush back.

3. The combination claimed in claim 1 in which the saddle is a step-likemember providing with a riser at the outer end to help secure the brushin place and a second riser at the other end in the form of a disc whichengages around and projects from the shank to support the handle inspaced relation when the tool is laid down on a surface.
